There is a lovely bold punctuation mark. What kind of input method is it?

Punctuation marks are an important part of written language and the least important part in middle school Chinese learning. When reviewing Chinese in high school, we must make some special efforts.

Punctuation marks are divided into dot and label. There are seven kinds of dots: pause, comma, semicolon, colon, period, question mark, exclamation mark, and labels include quotation marks, brackets, ellipsis, dash, book title, etc.
